LHCB ${{\mathit p}}{{\mathit p}}$ at 7, 8 TeV
1  Reconstructed in ${{\mathit \Xi}_{{{b}}}^{-}}$ $\rightarrow$ ${{\mathit \Xi}_{{{c}}}^{0}}{{\mathit \pi}^{-}}$, ${{\mathit \Xi}_{{{c}}}^{0}}$ $\rightarrow$ ${{\mathit p}}{{\mathit K}^{-}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$ decays. Uses ${{\mathit \Xi}_{{{b}}}^{0}}$ measurements from AAIJ 2014Z.
